Hi,
My wizard run out of battery completly yesterday, I brought it home and try to recharge it, but no recharging light will appear.
I left it overnight connected to the mains but to no appeal,
I also removed the battery for a few minutes and then plug again but no luck.
I´m not using the mains provided adaptor but my travelling kit, a proporta mains/usb adaptor and a retractable sync/charge cable with a mini-usb pin cos I´m back home for Xmas and I don´t travel with the mains.
I have read about problems with some chargers from Boxwave, but I have consistently using this charging conbination since October.
Any ideas, should I send it back to expansys to repair, or is there anything else I can try?
Thanks

same thing happened to me.. Supposely the phone will not charge from being completely dead without a charger that puts out 1amp. There is another method if you are a little brave... cut up an old car charger and hook it directly to the battery (red cord to + on battery and black to -) Read about it on howardforums and it worked like a champ. I only needed to jump the battery for about 30 seconds before I put it back in the phone and the amber light kicked on.. I was very relieved!!
Same happend to me yesterday. Simply plug the carger in and wait 1 or 2 seconds then switch the power button. After some seconds the carging light should switch on.
The wizard won't charge if it's switched off.
Export800,
you are a megastar,
I put apart a usb adaptor that I had built to charge my gps and I connected cables directly to battery for a minute and Voile,
tnx a million,

But if the battery is totally dead surely the unit wont switch on ? Thus its a catch 22 ??? There is no power to switch on and the battery wont charge totally dead.
Ridiculous if you were caught out away from a charger and ended up having to pull apart a usb lead to get things back to life.
If the battery is so low, that the wizard switches off itself, and you connect the charger, it won't charge, because it's switched off.
Use the power of the charger to turn it on, then charging will beginn (and also the device will boot).

Can anyone else confirm this works as there have been many people having this problem. Simple solution if it works.
Switch off your device completely (hold the Power Button) and try to charge: Nothing happens. Now switch it on - charging begins.
I have noticed that last week, when battery was very low and i know that i would need my wizard in about half an hour. So i switched it off completely, so that it would charge faster and noticed that.
Yesterday when battery was totally dead i remembered that and i switched it on.
Btw, doesn't it damage the battery, if you connect it to 12 V (!!)??

If I come across the problem will certainly be trying your method before I will be ripping into any usb leads
The same thing happened to me this past weekend. We were out camping and my MDA's (wizard) battery went completely dead. I had a USB sync cable for my laptop, but that would not revive the unit. I'm afraid the only way to bring it back to life is with the original OEM charger which has an output of 1 amp. Thanks for the post!
I had the same issue a while back. At first I thought the moto charger I had was dead but then I plugged in a old SMT5600 and it worked fine.
I left it plugged into my computer for a hour or so and finally I heard the "new usb device blip" from the other room and it started to charge. Guess I was lucky.
Same thing happened with my wifes SMT5600. The battery died and she couldn't get it to charge with her moto mini usb charger. I plugged it into my machine and a hour later the charging light came on.
I have heard that the Wizard will not charge from my laptop using a usb cable if it is completely drain. I find this to be NOT TRUE.
I ran out of juice twice last weekend. The thing about the Wizard is that, if it's completely drained, it will get stuck at the boot screen, and go no further.
Take out the battery to turn it off again. Put the battery back in, and then plug in your charger. DO NOT TURN IT BACK ON. It needs all the power it can get. Give it a minute, and you will see your orange charge light come on. Just leave it alone for several hours, and it will charge. This is my experience.
I got it! But, first the story.
None of the above methods helped me. I tried plugging it in to a big truck lighter, a pickup truck, even an ac adapter for my coleman cooler. Nothing!
However, I had a powered Pro-Clip mount that I had as a backup for the one I use. Guess what? THAT worked!
I think the cable makes the difference. Need to find the specs on those puppies. LOL
Thanks for the help.
well i let my phone die down. Forgot to charge it for a couple days of non use. Now its been on the charger for almost 24 hours and it still wont power on. I have noticed that my green charge light wont even power on. Any suggestions?

Well, letting your battery completely drain, won't damage your phone. More info please.
Thats all that happened. It went dead lastnight and i put it on the charger about an hour after it powered off. It did turn on for 2 seconds earlier but never went past the first post screen. Maybe a bad battery?
Hmm... interesting. Well, if a simple soft reset or holding down the power button doesn't work, I might try going to the cell phone shop and see if they have one on display you can swap batteries with to test the bad battery theory.
Also, this may seem a bit obvious, but have you tried a different outlet and have you just unplugged and re-plugged the power adapter in the phone itself?
actually, its more than likely the battery is too dead to be charged from the phone. There has to be some juice in it for it to be charged from the phone. You can either give the battery a 'jump' by using a cut USB cable (search for that solution) or buy a battery charger just for the battery. There are several on Ebay for real cheap.
well finally got home and was able to put in my spare battery. Fired right up. I have it on a charger right now with my spare battery. The old one is fried. I can get another one for cheap on ebay. Thanks alot for the suggestions!

The "dead" battery is likely just fully discharged. There are a couple of methods mentioned in the forums to fix, one is to use a 9v battery to "zap" it a few times and give it a little bit of charge, the other is to strip the wires off a USB cable and stick the +(red)/-(black) cables directly on the battery nodes and charge the battery a bit. I have done the second method myself (only last week in fact) and it works. All you need is enough of a charge for the phone to boot so you can continue charging with your normal method.
This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.
you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?
What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.
Next time dont power off ur X1,
if same happends then your battery is suffed.

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc
I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it
I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.
Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.
I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.
Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .
I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.
But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )
Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...
Hi guys
I've trawled through the forum and not seen a post with my problem
I got my X10 yesterday, got it home, left it on charge for around 5/6 hours. Gave me full battery. Used the phone all day yesterday, however when put on charge it wouldn't charge? I read somewhere that first time charge it may have to drop to 5% before would charge. So left the phone on for it to fully drain.
It turned itself off yesterday at about 4pm GMT - Plugged it into AC charger, sony erricson screen loads up, then it just says power down and turns itself off.
It has been plugged in usb on 2 different PC's, I've tried using different sockets around the house, I've taken battery out, checked terminals they are clean.
When plugged in the red led just flashes every few seconds and if I unplug the charger and goto turn on it just flashes 3 times.
It has been on 'charge' for over 14 hours now and still it loads up then powers down, occasionally it will flash up saying 2% battery left please connect charger.... (I've had it on charge over 14 hours..)
Could this be a dodgy battery? It worked fine yesterday from the intial charge when I recieved it.
Thanks
Stu
Seems to just be in a constant loop
I am going to ring carphonewarehouse at 11 when they open, but I'm guessing they'll just ask me to send the phone back...
sounds like cable or the wall charger itself or even the battery. best is to take it where you bought it and have them test what is the issue is.
Yeah, going to ring at 11 when the shop opens. Hopefully they can switch me a battery and charger in shop and we'll go from there. Just strange how it worked the previous night!

the x10 uses way more power during switch on and charging and this power cannot be suplied by the usb port.
use a wall charger instead...
Charger
When battery is drained, it can take a while for led to light up (giving impression of not charging). You may find that leaving it plugged in for 10 mins will resolve your concerns, the led will light up showing charge state.
External charger? Will it work?
the manual says that it can take up to 30 mins for the phone to even recognize charging. so if you see he red light flashing, its nothing to be concerned about.
i to have had the same problem, not charging and shutting itself down. i had mine 8 days and it was the first day i had used it, took it back t-mobile for repair and they sent it back to SE, 2 weeks later i had a report on what was wrong with it,
Apparently i dropped it or crushed it, just from picking it up and plugging to be charged, so now SE wont repair it. doesnt matter how much i argued with t-mobile that i did not drop it and they will always take the word of the engineer. so i am without a phone and still paying a £35 month contract, and in the long process of contacting t-mobile head office with the supply of goods and services act 1982, all i want them is to repair the damm phone. any one else got any more suggestions
Had similar problem downloaded USB drives and had to do a hard reset on phone. Worked fine after go to Sony Ericsson web check for support and downloads for x10.
I had the exact same problem. Phone would not take a charge and wasn't being recognized by my comp. I tried my battery from my X1 and it worked, and tried charging the battery via my X1 and battery was charging so it was obviously a problem with the charge port. I looked into getting it repaired via warranty but the Sony rep quoted me an unacceptable amount of time. I was able to get it repaired locally same day for $45. Works perfectly now.
Just to clarify for future readers, there may be two issues: (1) software, which per @RMD357, requires downloading the drivers again and doing a hard reset, and (2) hardware, which per @dunny, requires repairing the charge port.
Question to @RMD357, where did you find the drivers to download? I searched the SE website and could not find drivers.
Question to @dunny, what do you tell the repair person if you suspect that the charge port is an issue.
Thanks.
@visitador02 I just told the person at the repair shop my phone stopped taking a charge/being recognized on pc and that I tested different batteries, chargers, and cords so it was most likely a charge port issue. The guy at the shop told me that the charge port was probably damaged while connected to the USB cable and just replacing the part solved the issue. I believe the part cost like $10.
Hi there,
got a strange problem.
I plug in my N4 in the evening, it is loading up to 100% and there it begins to DISCHARGE (or in other words, stops to hold the battery at 100%) although still connected to the charger. In the morning I unplug the phone and have just around 70% left ... see attached screenshot.
Using stock charger and cable that came with the phone.
I hope this is not intended by Google? Running Android 4.2.1 Stock.
is this the only time it happened?
It is probably because of the charger. They definitely didn't include the best charger out there try another charger, you'll see improvements.

Thanks! Used my equipment (powered USB hub with another micro USB cable) from old phone until yesterday, and read about charging problems when NOT using the charger and cable that came with the N4. To see if that is maybe the problem I therefore unpacked the "stock" cable and charger - but it didn't solve the problem.
The most strange thing is, that it charges perfectly up to 100%! I would expect then that it stops charging to avoid overloading, but that holds the charge level at 100% until unplugged. I think this logic is not within the charger, but controlled by the phone itself (Software / Hardware Unit)?

Have the N4 about 1 week now and I realized this happening at least 4 times now. I'm usually plugging it in every evening and unplug it in the morning.
Its intended as a safety measure so it doesn't over charge when its 100 percent.... It's always been that way

Hmmm ... never experienced this 15 years mobile phones (at least 4 of them using Android and tons of different ROMs ...). What would be the purpose to plug in your phone in at 22pm, stop charging at 1am and begin the fresh day at 7am with again 30% loss of capacity? I would need to carry my charger stuff all day with me ...
As I said, I fully understand that it stops charging at 100% to avoid overloading - and also see the sense in this here -, but usually it should HOLD it at 99-100% until you unplug and not lose capacity while still connected to the charger.
Cheers
did you plug it into a USB hub that was plugged into a computer? that might be your problem. My N4 has issues charging from USB ports... it never holds charge properly.
This happened to me previously, ended up swapping my charger back to my Samsung OEM one and havent had the problem again.
Another time that this could happen is if you're charging via your USB port on your computer and you shutdown your computer which it will still show the charging icon but the status says not charging which could be changed by replugging the phone and/or having BIOS settings that enable usb power draw etc...
Just found this one ... maybe I'm not explaining my case very well, but it seems I am not alone ...

Yesterday I used the wall plug. All the years before I used a SEPARATELY POWERED usb hub. Even if the PC is shut, the hub provides power to the ports. Anyway, it doesn't matter - Charging is working perfectly on wall plug, usb hub, stock cable, non-stock cable ... before reaching 100% and phone disscharges. Picture in 1st post illustrates the disscharge while still "charging" (last bar at the bottom)
it's def. not normal. mine doesn't discharge, it can stay plugged in all night and it'll say 'CHARGED'

Exactly what I would expect! Now that I found the others on code.google.com having the same issue I think there was a batch of devices having it and that I might need to RMA ...
Well the reason why I was mentioning the charger (unless you've tested another one) is because I was using the original LG oem charger and for a while it would give inaccurate readings on multiple occasions. Example being I woke up (used wall charger) and it said 70-80% and the charge icon was still there but on the status it said 'not charging'. Another time was when it said 96%, unplugged and replugged and it charged to 100%. Then I use the phone for a couple of seconds and it drops down percentage again 96%~ and when/if charged it will say 100% again (giving a false reading).
I was thinking it was the cord because I used my bro's LG charger and it charged the phone 96, 97, 98, 99, 100 and not 96 -> 100% therefore the cord may have been the problem. Went back to my Samsung OEM charger and it has been fine since then and never had any discharging.
Are you using stock kernel?

I'm on 4.2.1 stock yes.
Thing is, that I'm not plugging it out! While being connected it suddenly starts to disscharge - Why the heck would you disscharge when you have a power source connected?! The "event" invoking the disscharge to me is the reach of 100%. Maybe this is a misbehavior of the overloading protection, to stop charging (as intended), but not restarting to charge at lets say 99% or 98% to get back to 100%. This would mean that when I'm using navigation in my car I would need to reconnectfrom time to time to trigger the charging again.

Yeah I know what you mean but its odd that I had this problem as well but disappeared when I swapped.
As for my USB/PC, that charges when the computer is on and off but when I turn it off, I would have to replug the phone to get it started again as it will have the same "charging icon" w/o it actually charging. My guess is that if the power source loses its power, even if its temporary it will stop charging. But when I using my Skyrocket a few months back I never had to replug the phone onto my computer to get it charging again but I do know that the computer will temporarily cut off power when you shutdown and bring it back to charge plugged devices. (didnt change any power states in BIOS).
So most likely it is something with the phone but it could also be a setting or some software error triggering a fail-safe or something.

I see definitely some issues in the charging logic in both of our cases here. You shouldn't have to replug your phone if you send your PC to sleep, as long as it still outputs the USB power. Since I would not expect the decision to charge or not to charge in the wall plug or in the USB hubs, I can only hope it is not a hardware problem of the charging electonic, but a software problem which could be patched. Also wouldn't I wonder if this has to do with the wireless charging option of the phone ...
come to think of it i had the same problem. charging from the PC when off via USB it would do the same thing as OP. charging through the wall works fine.
Well just found out I am maybe reposting the issue as I didn't find this initially ... similar (or same?) problem described here: http://forum.xda-developers.com/showthread.php?t=2031246
